BlockAcknowledgementMessage

public BlockAcknowledgementMessage(byte[] acknowledgementPayload)

Method Details

calculateBlockAcknowledgement

public static Integer calculateBlockAcknowledgement(Integer blockAck,
 int segO)

Calculates the block acknowledgement payload.

This method will set the segO bit to 1

Parameters:

blockAck - block acknowledgement payload to be sent

segO - segment index

calculateBlockAcknowledgement

public static int calculateBlockAcknowledgement(int segN)

Calculates the block acknowledgement payload.

This method will set the segO bit to 1

Parameters:

segN - number of segments

getState

public TransportControlMessage.TransportControlMessageState getState()

Specified by:

getState in class TransportControlMessage

getSegmentsToBeRetransmitted

public static ArrayList<Integer> getSegmentsToBeRetransmitted(byte[] blockAcknowledgement,
 int segmentCount)

Parses the block acknowledgement payload

This method will iterate though the block acknowledgement to find out which segments needs to be retransmitted.

Parameters:

blockAcknowledgement - acknowledgement payload received

segmentCount - number of segments

hasAllSegmentsBeenReceived

public static boolean hasAllSegmentsBeenReceived(Integer blockAcknowledgement,
 int segN)

Checks if all segments are received based on the segment count

Parameters:

blockAcknowledgement - acknowledgement payload received

segN - number of segments
